The student will be able to describe the types and methods of technical diagnostics, explain a diagnostic problem, choose the appropriate measurement method, select right sensors and measuring instruments for the specific application. Student will be able to specify parts of measuring chain to realize measurements and evaluate the measured data.

The student who enrolls this course should be able to explain the basics principles of sensors, understand the electronic circuits used in sensing and measurement technology, able to apply basic methods of electrical measurement (voltage, current, resistance, capacitance and inductance) and be able to assemble measuring chain with instruments as oscilloscope, function generator, DAQ cards for measuring of analog and digital signals and be able to prepare and use the LabVIEW developing tool. This course follows to courses in undergraduate studies BMVE and BSNI. Student should have such language skills to understand some educational materials in English.

Not applicable.

Teaching methods depend on the type of education which are described in the Article No. 7 of the Study and Examination Regulations of BUT. Techning methods include lectures and practical laboratories.

Up to 40 points for the laboratory exercises - laboratory reports from specific tasks.
Up to 60 points for final examination (written and oral).

The main content of the lectures covered the following areas:
1. Technical devices for diagnostics - types of diagnostics, sensors and analyzers for diagnosis, methods of testing.
2. Vibrodiagnostics - measuring of vibrations (vibration analysis, spectral measurements, averaging issues, detecting of natural frequencies).
3. Diagnostics of rotating machines, balancing of rotating machines, bearings fault diagnosis.
4. Modal analysis, vibration testing - modal testing, test by vibrations and shocks.
5. Acoustic measurement - acoustic quantities (sound power, sound pressure, sound intensity), near field, far field, acoustical holography.
6. Calibration of the sensors - accelerometers, microphones, gyroscopes; types of calibration (primary, secondary), interferometry, standards.
7. Thermovision diagnostics - thermography, measurement using thermal cameras.
8. NDT methods - ultrasonic defectoscopy, magnetic methods, X-ray methods, eddy-current testing, acoustic emission - methods of testing.

Not applicable.

The goal of the course is to expand knowledge in technical diagnostics. Selected measurement methods and their application in practice will be presented, e.g. vibrodiagnostics, acoustic measurement, ultrasonic defectoscopy, thermovision diagnostics, etc. The aim is to give to students an overview and understanding of advanced diagnostic methods by using special sensors, analyzers and other advanced instruments.

Definition of controlled education will be established by announcement published by course supervisor every year. Mandatory participation in laboratory exercises, in case of absence the exercise work can be supplemented with alternative exercise in same week or with a self-study of additional literature.
